Purpose

Oxford County is undertaking a Municipal Class Environmental Assessment (Class EA) Study to explore a range of possibilities for expanding the Tavistock Wastewater Treatment Plant (WWTP) in order to determine the most appropriate solution that will support the growing wastewater servicing needs within the Village of Tavistock in the Township of East Zorra-Tavistock.

Scope

Oxford County owns and operates the Tavistock WWTP, which provides treatment for residential and non-residential wastewater generated in the Village of Tavistock. The WWTP consists of three aerated facultative lagoon cells, one effluent storage lagoon, and four intermittent sand ﬁlters that polish the WWTP efﬂuent prior to discharge to the Hohner Drain and eventually the Thames River.

Oxford County is initiating a Municipal Class EA Study that will consider a wide range of enhancement options for the Tavistock WWTP. The Study objective is to identify the most cost-effective, environmentally sound, and sustainable approach to provide wastewater treatment capacity at the existing Tavistock WWTP to service the existing sewage flows as well as future growth in the Village of Tavistock.

This notice signals the commencement of the Class EA Study which will:

define the project;
identify and evaluate alternative solutions; and,
determine a preferred solution in consultation with the public, Indigenous communities and regulatory agencies.

Social, cultural, economic and natural environment impacts will be evaluated and assessed during the Class EA Study.

This study is being carried out in accordance with the requirements of Schedule C of the Municipal Class Environmental Assessment (2024), approved under the Ontario Environmental Assessment Act. Upon completion of this study, an Environmental Study Report documenting the process will be submitted to the Ontario Ministry of the Environment, Conservation and Parks and made available for public review for a minimum period of 30 calendar days.

Public consultation

Public, Indigenous, and technical agency consultation is a key component of the Class EA process and will be sought throughout the study. Project information, study documents and updates are available on the project website on Speak Up, Oxford! at www.oxfordcounty.ca/tavistock-wwtp-study

Public Consultation Centre (PCC) #1 was held on December 10, 2025 (virtual) and December 11, 2025 (in-person) to present the long-term wastewater servicing solutions being considered and evaluated, answer questions and receive comments from the public.
